So, I had a brew day today, got my dunkelweizen started. The store sells hop pellets in 1 oz increments, and they come in a vacuum packed pouch. I bought 2 packages of hops and used 1 and a quarter, so I have 3 quarters of a package left. The package wasn't cold when I got it so I don't think I need to refrigerate the leftover hops, but is it OK if I leave it in the package sealed with a rubber band? Would it be better to use my FoodSaver to vacuum pack it?
